GOTTFBE D OLSON, OF INTERNATIONAL FALLS, MINNESOTA.

METALLIC TIE AND TRACK-FASTENING.

To all whom it may concern Be it known that I, Gorrrnno OLsoN, a citizen of the United States, residing at International Falls, in the county of Kooc-hiching and State of Minnesota, have invented certain new and useful Improvements in Metallic Ties and Track-Fastenings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to metallic railway ties and rail fasteners.

The primary object of the invention is to provide an improved form of metallic: railway tie.

A further object of the invention is to combine with said improved tie, mechanisms whereby an improved railway track fastening is produced.

Yi ith these objects in view, the invention consists in the improved construction, combination and arrangement of parts of a device of the character specified, which will hereafter be fully described, and afterward specifically claimed.

In order that the construction and operation thereof may be readily comprehended, I will now proceed to describe my invention in connection with the accompanying drawing which illustrates an approved embodiment of my invention, and in which draws,

Figure 1 represents a transverse sectional plane cutting through the track rails, portions of the tie being broken away to show more clearly the openings into which the spikes are driven and the spikes being shown at one end of the figure before driving and at the other end after driving. Fig. 2 represents a top plan view of the complete tie and fastening, the rail being indicated in dotted lines. Fig. 3 represents a transverse sectional view taken on the plane indicated by the broken line 3-3 of Fig. 2. Fig. i,

represents in side elevation, one end of the tie, and, Fig. 5 represents a sectional view on the transverse plane 33 of Fig. 2, of a slightly modified form.

Like reference characters mark the same parts in all figures of the drawing.

My improved tie is of trough like form comprising a bottom 10 and upright flanges or sides 11. For some purposes the tie will be sufficiently rigid and strong with simply Specification of Letters Patent.

the side flanges 11, as shown in cross section in Fig. 5, but where the road is laid on rocky or stony ground, which renders it liable to uneven sinking, I deem it advisable to make the tie with a central rib l2, raised fro-m the bottom 10, as shown in Figs. 2 and 3. Each end of the tie is provided with a downwardly bent toe or flange 13, as best shown in Fig. 1, to enter the earth of the roadbed to prevent sliding longitudinally of the tie or transversely of the track.

At the points where the rails 1%. rest upon the tie, seats are built up for the support of the rails and the parts composing said seats, now to be described, may be for .aed integrally with the main body of the tie, or may be secured therein, as may be desirable. Between the walls of the tie are raised portions 15 which form, as it were, the walls of the tie seats, which walls extend nearly to the top of the walls of the tie, which are themselves raised at these points, as shown at 16 in Fig. 1. In these walls or seats for the rails is sutficient material to provide for a vertical opening 17 for each spike, which opening is curved at its lower end as at 18, into substantially semicircular form. Merged into the vertical opening 17 is a wedgeshaped groove 19 which is open through the side walls of the tie and is undercut as at 20. Upon the rail seats just described, are placed plates 21 of hard wood, with the grain in the direction of the length of the rail, and the rail rests upon this seat in order to give it a firm yielding support.

The spike which I use, designated at 22. is substantially square in cross section, and has the usual projecting head 23 to bind over the edge of the base of the rail when the spike is driven, and is formed of wedgeshape or rounded off at its point on the same side from which the head projects. The rail being seated in position on the hard wood plate, a key, as at 24, is dropped into the groove 19 and this key then forms the outer wall of the opening into which the spike is to be driven. The spike is now entered int this opening and driven, the point of the spike turning outward from the rail as shown clearly on the right-hand end of Fig. 1, turning up in the semicircular groove and holding the rail rigidly down upon its seat. The spike can be tightened at any time either by driving the wedge key tighter into its seat, or by driving the spike itself with a sledge hammer, every stroke causing more of the point of the spike to turn upward and continually increasing the power with which it clamps the base of the rail. In the hollow below the rail, I have provided drainage openings 25, which will carry ofl any rain or other water which may enter therein and a similar provision of drainage openings 26 is provided in the bottom 10 ot' the tie itself.

The construction of my improved tie and track fastener is exceedingly simple, strong and durable, and while I have particularly described the construction and arrangement of the parts, it will be obvious to those skilled in the art, that changes and variations may be made therein without depart ing from the spirit and scope of the invention.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent of the United States is 1. A metallic railway tie comprising a base and vertical flanges, said base being provided with rail seats consisting of substantially adjacent semicircular walls with their open sides toward the tie ends.

2. A metallic railway tie comprising a base and vertical flanges, rail seats on said base consisting of semicircular walls, and means upon said rail seats upon which the rails are adapted to rest.

3. A metallic railway tie comprising a base and vertical flanges, the base being provided with a central longitudinal inverted U-shaped stiflening rib and with rail seats consisting of substantially adjacent semicircular walls with their open sides to ward the tie ends.

4. A metallic railway tie comprising a base and vertical flanges, the base being provided with a central longitudinal inverted U-shaped stiffening rib and with rail seats consisting of substantially adjacent semicircular walls with their open sides toward the rail ends, said seats terminating below the tops of the side flanges, and hard wood plates on said seats.

5. A metallic railway tie comprising a base and vertical flanges, the base being provided with a central longitudinal inverted U-shaped stiffening rib and with rail seats consisting of substantially adjacent semicircular walls with their open sides toward the rail ends, said seats terminating below the tops of the side flanges, and hard *c-od plates on said seats having their grain running longitudinally of the rails.

6. A metallic railway tie comprising a base and vertical flanges, the base being pro-V vided with a central longitudinal inverted U-shaped stiflening rib and with rail seats consisting of substantially adjacent semicircular walls with their open sides toward the rail ends, said walls being spaced apart and the base of the tie between the walls being provided with drainage openings.

7. A metallic railway tie comprising a base and vertical flanges, said base provided with rail seats consisting of substantially semicircular walls with their open sides toward the rail ends, and provided with a semicircular longitudinal stiffening rib extending between said rail seats.

in testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
